Abstract
A semiconductor device with small variations in transistor characteristics is provided. The semiconductor device includes an oxide; a first conductor and a second conductor provided apart from each other over the oxide; an insulator in a region between the first conductor and the second conductor over the oxide; and a conductor over the insulator. A side surface of the oxide, a top surface of the first conductor, a side surface of the first conductor, a top surface of the second conductor, and a side surface of the second conductor include regions in contact with a nitride containing silicon.
